This invention relatesto broeders in which the use of fire heat or lamps is avoided and the main object of the invention is to pro-- vide a brooder of. this character in which heat retaining means are provided for sup-4 plying'a limited quantity of heat, so that the natural heat of the chicks is not altogether depended upon. v

F urther objects of the invention relate to improved hover means and to the'gcneral construction, whereby the manipulation, inspection and cleaning'of the broeder is facilitated. y

. The accompanying drawings illustrate the invention and referring'thereto:-Figure 1 is a perspective of the brooder with one o f the covers open to show the interior. Fig. 2 is a vertical section from front to back. Fig. 3 is a transverse section onthe line mS-aa in Fig. 2. Fig. 4 is a perspective of the hover. Fig. 5 is a perspective, partly broken away, of a `tubular center member for the hover. Fig. (3' is a horizontal section of the corner portion of thebrooder, showing the Ventilating moans; Figz Tis a pei'- Spective of the means for adj'ustably` `supporting the top member for the hover. Fig.

8 is ahorizontal section through the broeder.`

' The broeder comprises a case formed with a lbottoni l, sides 2, front 3 and back l, and'f also provided with a front cover 5 and rear cover G, said covers being hinged to a middle rail 7 extending from side to side of the brooder at the top thereof and said covers being respectively forwardly and rearwardly inclinedfrom this rail in the manner ot a.

roof. A' partition Wall 8 extending beneath this topv rail 7 from top to bottom of the case divides the case into forward and rear ortioiis or chambers, said partition wall eing provided in its-loiver portion with an opening oil door 9 for the passage of the chicks between said chambers. The. front Wall 3 of the case is provided with an opening for entry of the chicks into the broeder or their exit to thebi'ooder yard, said open* ing having a suitable closure erdoor 10. A feed trough 11 isprovded at the front of the case *having a feed chute 12 extending means for the chicks.

to the outside of the case and provided with a cover 13.

In the rear compartment or chamber `of the brooder there is provided a hover consisting of a cylindrical box or wall 15 having ani opening 1G foi' entry, of the chicks, said box resting on the floor 1 and being pro.- vided with al top member 17 preferably adjustable on the side or wall of box 15, for example, by means of forks 18 on the top 17 engaging with vertical guideways 19 on the wall 15, said forks resting on pins 2G inserted through perforatioiis 19 in the vei'- v tical guide-ways 19, see Fig. '7. Said cover member is provided with padding 2() on its Iunderface and with a circumferential curbeing of suitable soft fabric adapted to serve as a heat retaining Ameans andas a hover IA plate or false top 22 extends over the hover to further retain the heat and control the circulation within the hover, said top consisting of a board tting the inside of the rear chamber of the case and resting on corner members 23, said top board 22being cut away .as shown at 21 at the corners vand the corner members 23 beingfmade ofsheet metal or otherwise, in such manner as to provide vertical channels er passages in the corners of the said chamber of the case, openings 25 heilig provided in the sidewalls of the case at said passages for communication of air thereinto from the outside of the case.

The top board 22 has a central opening through which the air whiclipasscs from `the channels aforesaid into the space above the top board 22 may pass downwardly to the space below said top board and into the hover box 15. y

,Heat retaining means are provided for supplying heat in addition to heat furnished by the bodily heat of tlie chicks, said means consisting preferably ofajaior vessel 27 placedcentially in the rear compartment of the case and resting on the bottoni 1 thereofliy a protecting sheath or tube 28 being provided coiisisting, for example, of a sleeve of porous fabric, namely, cloth or felt over a skeleton 29, lsaid sheath surrounding the Vessel 27 and the top n1ember17 of the hover box having a central opening 30 to receive said sheath. Top plate 22 has a central orienizng 31 somewhat larger than the vesse 2 intowhich the chicks could huddle, and a' corner members 23 are plreferably 'if-rounded so as to be concave on eir inner faces, thereby avoiding any sharp corners similarrounded corner piece or member 32 1s provided 1n the rear corners of the front chamber, other corners of thesaid chamber being otherwise occupied. A- w dow 33 may be provided 1n the hm ed" cover 5 of the front chamber and and rear windows 34,35 may be pro- -v edfin the walls of the rear chamber. Inusing the brooder, thefvessel 27 will .be

filled with warm .or hot water and inserted wardly within the corner pieces 23 and overt f l the top member 22 and then down through the space or opening 3l in the top member 22, thereby supplying fresh airto` the'hover portion of the brooder in a gra-dual or distributed m'anner avoiding drafts and cold currents. By the provision ofa cylindrical hver box and the rounding of the corners of the chamber of the case,.I effectually prevent the huddling of the chicks into a corner and thereby avoid a serious source of loss.

What-I claim is v l. In a tireless brooder, a case provided with Ia compartment having a passage in the Wallthereof, a cylindrical Wall within said compartment and provided with a passage at one side, a hover member adj ustably supported within said cylindrical wall and provided With padding on its under surface and with a peripheral curtain, a heat-retaining means placed centrally of said hover member, said hovermember being provided with an opening to receive said means, a protecting tube of poorly conducting porous fabric for supporting said tube.

2. In a tireless brooder, a case provided witha compartment having a passage in the Wall thereof, ya cylindrical wall within said comp f tment and provided with a passage in thy side farthest away from the passage in thewall of the compartment, said cylinvsurrounding said body, and a skeleton means -jd'rical wall being separate from vthe outer wall of the compartment at all parts thereof I to leave a passage completely around said cylindrical wall, a hover member adjustably supported within said cylindrical wall and provided-With padding on its under surface and with a peripheral curtain, a heat retaining. body placed centrally o f said hover member, said hover member being provided Within the tubular sheath v28, which is placed' with an opening to receive said body, and a plate extending horizontally in said c ompartment over 'said cylindrical Wall, and over the space betweenV the cylindrical -wall andthe wall of the compartment, Q 70 8. In a relessnbrooder, a case provided,- With a compartment having a assa e in the wall thereof, acylindrical wa wit in said compartment and provided withv a passage in the side farthest away from the assagev in the Wall of` thecompartment, saidJ eylin drical Wall being separate from the outer wall of the l"compartment at all parts thereofto leave ja passage completel around said cylindrical wall, a hover mem er adjustably y supported within 'said cylindrical- Wall and provided with padding on its under surface and with a peripheralcurtain, a heat ,v

retainingbody ,placed 'centrally of said hover member, saidhover member being providedv 85 with an opening4 to receive said body', Va

vover the space between the cylindrical wall" and the lwall of the compartment, said plate being formed with an opening for the reception of the heat retaining bod said opening being ,suiiiciently large to eave an open space around said heat retaining body for ventilation of the space belowlthe plate, and means for'establishing Ventilating communication from the outside of the compare' ment to the space above said plate.y

4. In a tireless brooder, a' case provided.y

with a compartment having a passage in the IliadV wall thereof, a cylindrical Wall Within said compartment and provided with a passage at one side,l a hover member adj ustably supported withinsaid cylindrical Wall and pro- ,videdwith padding on its under surface and. 105 with a perlpheral curtain, a heat retai1nngjbody placed centrally ofsaid hover member', said hover member being provided with an; opening to rcceivesaid bodya plate extcnding horizontallyin saidrcompartmentl over said cylindrical wall, said compartment being provided with corner pieces forming verticalchannels at the respective corners, and said plate'being cut away at the corners f to provide openings from said channels to V the space above said plate, and said plate being further provided with a central open- -ing around .said heat retaining bo'dy, the said compartment being provided with openings in its walls-for communication of air from l120 the outside of theV case to the said vertical passages. In testimony whereof, I have hereunto set my hand at -Los Angeles, California, this 10th day of February, 1910.
